Green River Ferry Improvement Projects
Work is continuing to complete the last steps of a vehicle ramp extension project for the Green River Ferry. Additional projects in the Green River Ferry day-use area include the construction of a new canoe and kayak launch site and a foot bridge on the Echo River Springs Trail. Some closures may occur due to construction in this area of the park.
Mammoth Cave Trail Rehabilitation Project
The Grand Avenue and Wild Cave Tours are temporarily closed. The trail work will improve the walking path, stairs, handrails, seating and resource issues along approximately two miles of trail. The entire project is scheduled to take 18-20 months to complete. Other tours in the park are open to visitors as usual.
